Clean Air in London’s Mission is to achieve urgently and sustainably full compliance with WHO guidelines for air quality throughout London and elsewhere. It works closely with other campaign groups and a wider network of supporters and volunteers to identify and build understanding of the most important issues and encourage decisive action on them. Clean Air in London is a not-for-profit organisation funded by donations, sponsors and other supporters. It is not a charity in part because a registered charity is not allowed to have political objectives or take part in political lobbying (other than in a generally educational sense). Clean Air in London may wish to participate in such activities. Clean Air in London is a company limited by guarantee, registered in England and Wales, with company number 7413769 and registered office address Thames House, Mere Park, Dedmere Road, Marlow, Bucks SL7 1PB
